Eldery woman takes her eldery husband to the dr. for a checkup. When he finishes, the dr. calls the woman in and ask her "what have you been feeding this man? He's in terrible shape". The woman replies" We are on a fixed budget and can't afford the right foods so we mostly eat dog food". The dr. tells her "I'm sorry, but if you continue feeding him dog food, it will kill him". A few weeks later the dr. meets the woman on the street and asks about her husband. She replies that her husband died. The dr. says " I hate to say I told you so, but I told you that dog food would kill him" "No" she replies, "It wasn't the dog food, he was laying out in the street, licking his balls, and a truck ran over him".
